Well,I saw this in other forum but I couldn't resist to make a thread here too...
It is about a website called pennystocks.la which is currently ranked on top 10 ,in 2# page for the keyword "penny stocks"(135.000 searches per month).How did the rank?

First they did this - it hit the front page of Reddit under the idiotic "Internet is Beautiful" subreddit. They got 20k backlinks - no doubt from some big guys - and then once the hype died down, they dropped some anchor text into the page - see if you can find it.
